New Revision: 193159
URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=193159
Log:
* tree-ssa-loop-niter.c (find_loop_niter): Remove just_once_each_iteration_p.
(maybe_lower_iteration_bound): Initialize not_executed_last_iteration to NULL
* tree-ssa-loop-ivcanon.c (canonicalize_loop_induction_variables): Skip
just_once_each_iteration_p; record estimated bound when loop has only one
likely exit; test just_once_each_iteration_p before IV canon itself.
